[QUOTE="Mark DeArman, post: 145920, member: 950"] Re: Correct feeder cable for distro It seems like the most obvious is a load fault ;-) Wires in an extension cord, in close proximity, the field is going to cancel? The only issue would be common mode noise coupling into the loop, correct? EDIT: It seems this myth comes from auto-retracting cord reels which you find mounted on the walls in shops. In this case, you have cheap cables wrapped really tight on the drum. (Harbor Freight?) These products are normally labeled separately for wrapped and unwrapped so they can be UL listed. Cheap versions are most likely below the minimum bend radius for the wire on the inside of the spool. So you have stressed wire, tightly wrapped, with no ventilation. (Not to mention, how many times have I tugged on my drop light?) This is a little different than having 25' 12/3 SOW loosely coiled with with a 2ft radius on the floor. Lots of talk about L21-30 up above breaking out into single phase circuits? Just remember the neutral is only rated at 30A. [/QUOTE]
